TILE-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 737,843, dated September 1, 1903.

Application filed November 18, 1902- Serial No. 131,881. (No model.)

To all whom, it may concern:

Be it known that I, WALLACE A. Hours, a citizen of the United States, residing in Oakland, county of Alameda, State of California, have invented an Improvement in Tile-Making Machines; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to improvements in machines for manufacturing drain-tiles, conduit-sections, and the like. Its object is particularly to provide an apparatus suitable for the manufacture of pipe or tiling from compositions containing asphaltum, sand, and the like.

It consists of the parts and the construction and combination of parts, as hereinafter more fully described, having reference to the accompanying drawings, in which- Figure 1 is a general elevation of my invention. Fig. 2 is a partial plan View of same. Fig. 3 is a bottom view of ring with guide projections. Fig. 5 is a cross-section of cylindrical base piece. Fig. 6 is a transverse section of mold Fig. 7 is a segmental disk for insertion to form Ts. Fig. 8 is a view of mold and attachments.

A represents the framework supporting the various parts of my apparatus. This frame is preferably constructed of angle and channel iron and properly braced, so as to withstand the heavy usage that it will naturally be subjected to. Suitably journaled in this frame is a vertical shaft 2, supporting a table 3 and rotated by any approved means, as the worm-gear 4, for it is desired that the ta ble should have a slow movement and capable of being stopped instantly. The edge of the table is supported upon rollers 5, running on a suitable track or support secured to frame A. Upon the table are disposed one or more molds constructed as follows: 6 is a cylindrical base-piece having inner and outer concentric walls connected at the bottom at intervals to form an annular box orsocket. A ring 7 is movable in the space 8 between This ring has a series of guide projections 9, extending down through the holes in the bottom of space 8, and certain of these projections carry rollers 10 for the purpose to be described later. A plunger-core Fig. 4. is a cross-section of same.

11, having a conical upper end 12, is recipe rocable centrally through the base-piece 6. The movement of the plunger downward is limited by a suitable stop, as 13, carried by the table and engaging the lower end of the core. It is not intended that the core should drop below a point where the base of the preferably a mixture of asphaltum, sand, and

other ingredients previously rendered plastic by heat and having the quality when cooled of setting into a hard resistant mass. Suspended above each base-pieoe is a cylinder 15, adapted to fit within the upper end of the base-piece 6 and to form an annular space (corresponding to the exact thickness and shape of the finished tile) between its inner surface and thevcore when the latter is projected up through the base-piece to its full limit. The lower end of the cylinder is formed with an annular shoulder 16, corresponding to the upper beveled edge of 14.. The part 14 is for the purpose of forming the flange of the tile. the vertical guides 17, carried on the table, and is suspended by ropes 18, passing over these guides and having counterweights 19 on their other ends by which the raising and owering of the cylinder may be facilitated. When the base-piece 6 has been filled with the hot plastic material, as above described, the cylinder 15 is lowered until the flanges 20 on the outside of the cylinder rest on the table. These flanges are then engaged by the dogs 21 to prevent the cylinder from being lifted when the core is reciprocated upward. The insertion of the cylinder into the mass within the base-piece and the subsequent action of lifting the core causes the material to fill all the space intervening between the core and the cylinder. The lifting of the core and the compression of the tile is effected by means of the hydraulic presses 22 23, disposed one above and one below the table in the The cylinder 15 is movable between tile from cylinder 15.

plane of the path of the molds. On filling a base-piece the table is moved to bring the base-piece immediately above press 23 and beneath press 22. Press 23 is then operated to lift the plunger-core 11 till it projects above cylinder 15. A ring 25 is then inserted from the top between the core and cylinder 15, and the conical cap-plunger 26 of press 22 is operated to force the ring down to compress the material and give permanent form to the tile. The pressure on 25 continues until the point of core 11 projects up into the cap 26. In this latter upward movement of the core the ends of the projections 9 are engaged by the plunger of press 23 to lift the ring 7 and compress the flange end of the tile against the downward pressure of ring 25. Press 22 is then released, the dogs 21 turned to free flanges 20, and upon a further upward movement by press 23 ring 7, the tile, the core, and cylinder 15 are lifted a couple of inches. This serves to free the flange of the tile from wall 14 of the base-piece. The dogs 21 are then turned to interposea stop to the return of the cylinder to its original position in the base-piece, press 23 is partially released, plate 27 is turned across the open-' ing of cap-plunger 26, and press 22 is operated to push core 11 downward and free it from the tile. The continued downward movement of the plunger of press 22 causes ring 25 to be engaged and moved to free the If desired, the latter may be made with a slight taper on the inside, as shown, so that at the end of the lastdescribed movement a space will be left between the tile and the cylinder through which water may percolate and cool the tile. It will be noted that the tile has now been freed successively from the base-piece, the core, and the cylinder, and the core on leaving press 23 is free to fall by gravity to its first position of rest on stop 13. The table is then rotated to bring a succeeding base-piece into position between the presses, and the operation above described is repeated.

While I have shown but two base-pieces for purposes of illustration, there would as a rule be four or more base-pieces mounted upon the one table, giving a consequent increased capacity to the machine.

During the rotation of the table over the cam-guides 28 (by which latter the rollers 10 on the projections 9 are engaged to lift ring 7 and discharge the tile from the base-piece) the ring 25 and cylinder 15 are lifted out of engagement with the tile and a stream of water played upon the tile to cool it and cause it to set, so it may be handled subsequently without fear or likelihood of damage. Before passing from the guides 28 the tile is removed from the table, and on leaving said guides ring 7 falls back again into position in the bottom of base-piece 6. 1

If it is desired to make a tile to receive a lateral branch after the manner of a T, a concaved segment 29, of a diameter equal to the outside diameter of said branch and of a thickness equal to the space between 11 and 15, may be inserted into the mass of material between 11 and 15 before ring 25 is put in place. After the tile is completed the part 29 can be knocked out, leaving a hole to receive the branch section.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-
